There were three variants of the electric driver seat in the 124 which is the electrical basis of a gen 2 126.

First there was the non memory seat. All power for the motors goes straight through the switch. All passenger seats are like this across the entire 124 range.

Second there was the early 124 memory seat. The switch only operated control wires to the logic box under the seat. All power switching done in the box. Individual wires from each switch contact to the logic.

Third was the later 124 memory seat. The switch had logic in it and a data bus connection to the under seat controls. Only a few wires between switch and box.

I would suspect an early 126 would have a seat of the first or second kind.

I would obtain ETMs for your car and the donor and see what you have side by side.
